Open Roberta: Beta 1.3.0 Released

customLogo.gifA new version of Open Roberta (beta 1.3.0) was recently released, and includes a 2D simulation of a robot with differential drive.

This is a simulation of a two-dimensional robot model equipped with two wheels (differential drive), an ultrasonic sensor, a touch sensor, a color sensor, and the display of an LED. In addition, different environments can be chosen. The NEPO programming language can be used to program the simulated robot.

Open Roberta is a free, cloud-based programming environment for the EV3 and is available at:

Open Roberta and “Roberta – Learning with Robot”

The aim of Open Roberta is to lower the barriers of programming for kids, teachers, and schools and to set up a open source community. Open Roberta is part of the Fraunhofer Initiative “Roberta – Learning with Robots” ( The Roberta initiative aims to engage and motivate girls and boys to take a sustained long-term interest in information technology, technology, and the natural sciences. The Roberta training concept defines “sustained long-term motivation” as simultaneously imparting cognitive knowledge – in this instance from the world of STEM topics – and positive emotions. Only if both are achieved at the same time do students learn – or phrased differently achieve sustainable results.

Open Roberta Lab

Open Roberta Lab is the cloud-based and open source graphical programming environment that is at the core of Open Roberta.


NEPO is a meta programming language developed by Fraunhofer IAIS, based on Blockly and inspired by Scratch. The aim of NEPO is to be able to program different robot systems with only one programming language. Fraunhofer IAIS plans to include two other robot systems before the end of 2015.

Fraunhofer Institute for Intelligent Analysis and Information Systems IAIS

“Fraunhofer IAIS develops tailor-made IT solutions to support companies and organizations optimize products, services and processes, as well as to implement intelligent information and knowledge management. There is a particular focus on the analysis, access, and targeted use of large data quantities, new media technologies, and solutions for innovative business and security processes. Fraunhofer IAIS is one of 65 Fraunhofer Institutes across Germany. Each institute has its own research focus.”

Fraunhofer Society

“Fraunhofer is Europe’s largest application-oriented research organization. Our research efforts are geared entirely to people’s needs: health, security, communication, energy and the environment. As a result, the work undertaken by our researchers and developers has a significant impact on people’s lives. We are creative. We shape technology. We design products. We improve methods and techniques. We open up new vistas. In short, we forge the future.”
